T all whom. t may concern:

Be it known that we, EDWARD ADELL, of

.Orange in' county of Franklim vState ofl Massachusetts, and CARL A.BniNK, of Uran'- ston, in the county of Providence, Stateof RhodeIsland, citizens of the United States, have invented certain new anduseful lin-l provements in Cop or Bobbin Holders, of

r which the following is aspeciication.

vide a bobbin-holder which may be moreand conveniently applied and onwhich itA will be more: securely held to control `its rot-ation indelivering the yarn or `thread therefrom. v-

Another object of the-invention'is to proreadily placed onand removedfrom the spindles of the hraider-carrierS, whereby to'- facilitate theapplication of thebobbins 'to the holder and the-doi'ling of the emptycoptubes therefrom.

Itisv to beiinderstood, however, that'the present 'improvements are also'adaptedto be applied to the spindles ,or mandrels-'of other textileapparatus,` such for instance as winding machines. t is the usualpractice to control the delivery of the yarn from the bobbins onthebraidercarriers by means of a pawl-mechanism which operates to pei'-mit an intermittent rotation of the bobbinholder under the pull on theyarn. For this A' purpose they bobbin-holder isgenerally provided with aratchet-disk or head with which i .A Specification of Letters Patent.1PM-@umd July ,25, 19220 bfobbinlh'older comprises in general va tubuf--lar'sleeve' or mandrel 2 adapted' for insertion in the 'bore ofthetube on which the cop orv bobhin is wound, and a ratchet-disk orh'ead 3mounted on the endfof the sleeve. .Als a :novelv feature of the 4present improvement l toadaptthe bobbin-holder to rotate freely onthespindle of the braider-carrier. The above named essential'eleinentsof thedeviee comprising ,the outer 'sleeve 2, the ratchethead 3 and theinner Sleeve or bushing .4 are preferably constructed from sheet-metaland united by an ingenious method of .construction, whereby to provide aparticularly staunch reinforced structure capable of resisting hardusage when the bobbin-holders are dropped or tossed about during theirhandling. A i

Referring to Figs. 5 to 9 inclusive, for convenience of description theratchet-disk or head 3 may be considered the main element or base of thedevice since it serves as a foundation for the other parts which areattached thereto. The head\3 is preferably constructed from a circularblank B, see Fig. 5, which is cupped out, as illust ated in Fig. 6, toform a. fla-ring rim or fiange 5 surrounding its periphery. At thecenter of the head 3 is a circular opening 7 within which the inner tube4 is held7 and at the sides thereof are rectangular slots 8 adapted toreceive suitable end-lugs 9 on the outer sleeve 2 which are rivetedtherethrough to secure the parts together. in the manner as hereinaftermore fully described. The blank B is also punched or perforated with aseries of circular holes 10 arranged concenti'ically of its axis andadapted fora purpose as later ex plained.

To form'the ratchet teeth 11 on the head or disk. 3 the rim 5 of theblank B is slit through at intervals and cut away from the main portionof thel disk to provide ears 12 which are bent or folded around intosubstantially horseshoe shape, as sho-wn in 7. As here illustrated. theears 12 extend inwardly substantially radial withthe'axis of the diskand their ends are notched o-r cut away at the top to form lugs 13 ofless depth than the main portion of the ears, seelFig. 8. At the nextoperation the ears 12 are bent or forced toward each other and foldedinto substantially parallel overlapping relation, asvshown in Fig. 9. Itwill be note-d thatl when the ears 12 are bent into this relationtheir'end lugs 13 will be brought into register with the holes 10 in thedisk 3. At thenext operation the metal in the lugs 13 is crushed orextruded down through the holes 10, as shown in Figs. 2 and 10, thusforming a bond or tie between the extrem-v construction the ears 12 arefirmly anchored to the disk at their inner ends, while their outerfolded portions are united to the periphery of the disk 'at the pointswhere they join therewith@ ln this improved structure the double ears 12form the reinforced radial teeth 11 projecting from the face of the disk3 to adapt them to be engaged by the pawl or detent which controls therotation of the bobbin-holder in the manner and for the purpose as wellknown in the art.

Referring now to Figs. 1, 2 and 3, the

outer sleeve or mandrel 2 on which the cop .outwardly from thecylindrical end portions 17 of the sleeve 2, see Fig. 2, and extend sub-75 stantially parallel tothe axis of the holder throughout substantiallytheir full length. lVhen the paper or fibre cop-tube C is slipped on'over the sleeve or mandrel 2 the springmembers 16 are compressedslightly and at 8O 'the same time their sharp edges 18, see Fig.

3, will bite into the .bore of the tube C whereby to firmly grip thelatter to secure the bobbin to the holder.

YIt has before been noted that one end of the sleeve 2 is provided withprojecting lugs 9- and, as shown in Figs. 2 and 10, these are insertedthrough the slots 8 in the disk 8 and headed over to rivet the tube tothe disk.

The outer sleeve or mandrel 2 is further held to the disk 3 by means ofthe inner tube or bushing 4 which serves as a reinforcing element 'inthe manner as next explained. Referring to Figs. 2 and 4, the bushing4may. be constructed from seamless 95 drawn tubing or may be rolled fromat stock as herein shown. The main portion of the tube 4 is ofappropriate size to adapt it to fit freely onto the spindle of thebraider-carrier, but at its lower end the tube is flared or belledoutwardly to provide an enlarged mouth portion 19. At its upper end thesmaller main portion of the tube is inserted through the axial hole 7 inthe disk 3 while its lower enlarged end' fits closely within the end ofthe outer sleeve 2. After the tube 4 has been applied to position inthis manner its ends are swaged or headed over at 20 whereby to secureit in place; and in this way the tube 4 serves as atie and re- 110inforcing element for the outer sleeve 2 and materially strengthens andstiffens the whole structure.

Midway the ends of the inner tube 4 is a stop-limit or rest 21 for thespring-members 115 16. The stop or. rest 21 consists simply of anannular abutment or raised "ring against which the spring-members 16"bear when they lare compressed toward the axis of the holder'. Theabutment or annulus 21 is pref- 120 erably formed by swaging out themetal of the inner tube 4 in a convex ring, as shown in Fig. 2, or ifpreferred a wire ring 22 may be applied to the periphery of the tube 4as illustrated in Fig. 4. l The purpose of this 125 stop-ring or rest 21is to limit the contraction of the spring-members 16 to preventthem'from being bent inwardly to such an extent that they will fail toreact to the outermost limits. It is well known that spring- 130 metalwill flex and react to a certain extent,

' but beyond this limit it becomes set and loses more readily appliedthereto.

its resilience, so that the stop-ring 21 is provided to prevent thespring-members from being contracted beyond the safe limit. The purposeof the enlarged bell or mouth ,19 at the bottom of the sleeve t is toprovide for an easier entrance for the end of the carrier-spindle S,Which is shown by dotted lines in F ig. 2 to illustra-te the manner inwhich the carrier is slid over it. By this provision the application ofthe bobbincai'rier to the spindle is rendered much easier and moreconvenient, tending to a saving in time and elfort on the part of theoperator. be readily slipped onto and off from the spindles so thatthe-oops or bobbins may be This saves the operator from reaching in overthe machine to a'pply the bobbin to the holder when the latterjis lessaccessible than when held in the hand;- This improvement is ofparticularly advantage in facilitating the.

doliing of the'empty cop-tubes from the holders since they frequentlystick'and require considerable force to pull them 0E. Moreover, thismethod of applying the bobbins and doiiing the tubes eliminates thedanger of bending the spindles, which is to be avoided so that theholders AWill turn freely and run true thereon.

It will be observed that our improvement provides a bobbin-holder ofparticularly light yet staunch and rigid construction, ca-

vpable of resisting rough handlingand hard usage and proof against Wearor deterioration. The end-liead or ratchet-disk on the holder is muchlighter in Weight than the usual cast-iron ratchet, yet possesses thenecessary strength and stiffness in its reinforced teeth.I The outersleeve of the holder provides a particularly eiiicient gripping-means.for securing the' -bobbin in place on the holder and the resiliency ofits spring-members is preserved-from 'deterioration by the stop-ring orvabutment which prevents them from being crushed outv of shape. The innertube forms a straight smooth bearing for the holder on its spindle, andinaddition serves as a tie or strut to The several parts of the deviceare Secured together by a novel method of constructionvwhich renders.them mutually reinforced and strengthened, While the complete deviceisdesigned for economical manufacture to cheapen its cost.

Various modifications may be made in the form and arrangement of theparts of the device Without departing from the spirit or scope of theinvention, therefore Without I limiting ourselves to the exactembodiment herein shown and described, We claim:
